COMPANY, `F NEW YORK, N. Y., A CORPOM'I'ICN OP NEW YORK;

To whom it may concern.' l'

a citizen of the United States, residing at Cleveland, in ther county of Bradley and e State of'Tennessee, have invented certain new and. useful Improvementsk in Distilling Systems, of which the following is a speci- My inventionl relates to certain new and useful im rovements insystems particularly adapedor distilling kpotable water from yses water, and the obJectof my invention is,V

o to provide a system whichis particularl boilers. As result of this the latent heat contained in the vapor from the evaporators is utilized thus economizing, the' coal consumption of he vessel. In my'system only the vapor from the evaporators alone is used to heat a feed water heater of the ,surface type, Aplaced preferably on. the

'iso

n the evaporator.

discharge side of. feed pump, and conse- 'quently potable` water is supplied.l

A further object of my inrentin is `to utilize theV exhaust from auxiliary engines to preliminarily heat the feed water before it enters the final heater where it is heated to a high temperature by theyapor from Another advantage of my system is that by using the vaporfrom the evaporators in the. feed water heater a comparatively high pressure may he maintained upon the. shell of the heater, sothatvthe feed water Celivered to the main boilers is of a very high temperature. For instance if a pressureof thirty pounds above atmosphere is carried inthe evaporator a pressure of from six to twenty pounds may be carried-.on the shell of the feed water heater which-'will give the feed water a temperature of 200" to .250cl `Fahrenheit when 1t passes from the heater.

. With these andl other objects in view my 'invention consists in certain Acombinations and arrangements of parts, one foi-xn of which will lbe first described; in connection with the accompanying drawings and then the inventhm particularly` pointed ont. in the appended claims. l -Referring to the drawings wherein the saine part is designated by the same refernIsrILLmG SYSTEM.

illust-rates diagrammatically` one arrangey ment of my system. Y e

1 designates an evaporato'f'orfwater or `shown being of the well known'Baird type in which a steam coil 2 is' employed surp- Aplied by steam from any source` through pipe. o

4 yis the outlet from the'stemi coil and,`as indicated, runs to the feed Wuterftank in order` not to waste water. Y

5 designates a .separator which preferably is of the form shown and described in my Patent No. 864,158, granted August 27, 1908,

Whichfeomprises a. closed vessel having anrinlet pipe 3 which reaches nearly' to the bot-l tom thereof, and an outlet pipe 5 from the topthereof; also a screen of tine wire' mesh within said vessel as fully shown and described in my said patent, though any other form 0f separator desiredmay be substituted therefor. This Aseparator' is connected to the evaporatorv by means of the pipe 6, so that vapor froni the evaporator will pass into the separatmand have any waters-r liquid carred by the vapor separated therefrom.

7 designates the final feed water heater for the main boilers, and is of any ordinary o .desired construction of the surface type.` The shell of the'heater is'connected to the sep' f amtor by means of the vpipe fvviereby the va or a ter passing through the separator is V`de ivered to the shell of this heater. t

9 designates'the rst or prelin'iina'ry; feed' water heater which may he of any ordinary or desired type. `T he shell of this heater is preferably supplied with'exhaust steam from an -auxiliary engine through thepipe 10. The water condensed in the heater 9 1s ds-` charged' through the pipe 1-1 preferably to the feed water tank indicated, in order vthat it. may not' be wasted.

1|' f The feed wat er to be heated enters the 'preliminary heater 9' from' the feed water-tank l'iy the pipe l2, and is discharged from this heater by the pipe 13 into the final heater 7 from rwhich it is delivered by the pipe 14 to i Y the boilers. The Water-condensed in the shell of the linalaheatcr isdis -harged 'through a pipe 14. pre ferabl v provided w ith a trap 15 of any ordinary or desired construction, into a cooliugcondenser 16 of any ordinaryy or Vdesired construction, -froni which theii'at'ery passes, for instance discharging the water used to cool .the con-l denser 16.

p ze

`wall ofthis heater a pipe 2O in which I pl Y, 'a pressure regulating valve 21 of any ordi nary or desired construction, siiidpipe lead- ASI preferito use such :i pressure in 'the final feed water heater 'Z as will del'iier the feed water at a high temperaturenvv isimpossible to always condense' all the-vapor in this neate'r. I therefore ccanectte the ing to a condenser 22 of any ordinar or de sired construction where all vapor from the heater 7 1s condensed. The water from the -condenser 22 is discharged from a suitable -pipe 23 to a tank, or disposed of in` any other way desired.

As all the steam deliveredto the preliini;

nary heater 9 may not be condensed therein,

`I prefer to connectto the Wall ofthis heaterV a pipe 24, in which is placed a. pressurek regulating-valve 25 of any ordinary oi-desirecl construction, said pipe-leading 'to a-veondenser 26, of any ordinary or desired coni vstruct-ion, whereby all vapor from the heater '9 is condensed. The water from the con'- denser 26 is discharged from a pipe'27 to the feed water tank or disposed of in any other wegdesird. H.

alt water or other liquid to be evaporated is Afed to the evaporator 1 by the feed pipe 28` and the evaporator may` bc blown out. whenr desired by opening the valve in the waste pipe 29. The separator 5 may also be blown out by opening the valve in the waste pipe i 30, or may be discharged through a trap yconnected to thejvaste pipe. f

`It is, to he noted that the evaporator, sep-` arator, heaters, condensers, etc., may Vall be of any ordina ry or. desired construction, as their articular construction forms .no part oLfpmy invention, which consists in the combination and arrangement of these 'well known ele;- ments to form a new and improved combination which will produce better results more fthev feed water heater to heat the feed vanter up to n. high temperature may be maintained and which will utilize the heat' given they economically than has heretofore been possible.

From the above described constructionit will be seen that. I have devised a. system in which thenecessary pressure on the shell of vapor in the eva iorators without in any way contaminating t e distilled water, and since the water distilled by my system is not cont'aminated it' is of the same quality as would be produced were the vapor condensed b y sen water which is passed over-board, as` is.
